Description
Technical field
Present disclosure relates generally to valve actuator, and relates more specifically to the control system of the valve actuator for comprising wireless human machine interface.
Background technique
Valve actuator is used for operating valve, and with many shapes, size, form manufacture, and there is multiple application.Valve actuator can by the driving of hydrodynamic pressure artificially, electric drive, operation, and its axis directly or is indirectly connected in fluid-operated piston or other hydraulic systems.
Control system or its be usually positioned at least partially on the shell of valve actuator, for controlling through the flowing of valve, valve actuator is connected on valve via man-machine interface (HMI).This control system allows various function and the structure of user's control valve actuator, operational diagnostics on valve actuator, and the state of test valve actuator.
Substantially, this control system has control inputs, and e.g., knob, it mechanically operates to dock with the control system of valve actuator.In some cases, non-contact control input such as magnetic turn button allows to use external knob, and control system seals in valve actuator simultaneously.In this construction, the rotation of the one or more magnet in magnetic turn button changes the magnetic field produced by knob.Sensor, as the hall effect sensor in valve actuator, senses the change in the magnetic field of knob, and the input signal of correspondence is provided to control system.This structure can be particularly useful under the outside of valve actuator is in the environmental conditions of wet environment, and in wet environment, fluid or other pollutants can connect internals close to valve actuator via direct mechanical, as by potentiometric axle.
But non-contact mechanical connects as magnetic turn button still can have narrow limitation.Such as, the magnet in knob and the distance between the hall effect sensor in valve actuator must closely control, and make sensor can detect the movement of knob.If distance increases too far away, then sensor can not detect the magnet in knob.In addition, this magnetic turn button needs to move through the camber line limited substantially, to be sensed rotation.Therefore, must pay special attention to guarantee that pollutant such as water and ice can not be accumulated in movable surfaces in design and operation, this can stop knob to move fully through the camber line of its design.And, can detect and only limit the functional of knob along the magnetic sensor of the movement in a curve limited.
Finally, in order to prevent knob due to vibration or the input of other unexpected physics accidental movement, knob and sane spring and click-fit may be needed, to reduce the possible of knob accidental movement.But this sane spring and ratchet need user to be applied on knob with relatively strong power to move them.Therefore, after the one or more actuator of configuration, knob is exerted a force the discomfort that can cause to a certain degree like this, because above-mentioned one or more actuator all can need the knob of greater number to move the configuration of valve actuator.In addition, the spring in knob and ratchet can lose efficacy, thus made knob by gravity or vibration movement to some unexpected positions, and actuator can be placed in some unexpected operator schemes again by then.
